To all whom t `mag/concern.'

Be it'known that I, LEWIS T. CANEIELD, a citizen of the United States, and resident of Chicago, county of Cook, and Stateof Illinois, have invented certain" new and useful Improvementsin Car-Roofs, ofV which ,the followingV is a specification, and which are illustratedfin the accompanying drawings, forming a part thereof.

The invention relates to roofs for'cars, and

is especially adapted for use in connection with freight cars'.

A The object of the invention is to provide a roof which is made entirely of sheet metal and in which the framing ordinarily used, consisting of a rigid pole,carlines and purlins, may be dispensed with. V

The further object is to provide which shall be rigid.

One form of construction exemplifying the invention' is fully hereinafter described a roof and is illustrated in the accompanying drawings, in which- Figure 1 's a partly broken away; Fig. 2 is a cross sectional detail, on

Y. 3 is a detail longitudinal section ofthe roof,

taken a little to one side of the ridge thereof; and Fig. 4 is a detail of one of the plates of which the roof is composed.

The roof is formed of a plurality of sheet niet-al plates, each plate extending from the ridge of the roof to the eaves of thecar and having its edges folded or anged downwardly, adjacent flanges of the several plates lying side by side and being secured together, the eave angs being folded down over the outer surface of an eave plate, and the anges at the ends of the car being folded down upon an end plate. y

The 'roof is especially adaptedfor use in connection with metal cars, as the framing of suchrars is' itself rigid and not subject to distortion Box carsil vided withsa. 411g as 13.0,.whicl1anay be of steel rolledl t'o any desired form, the Ysiding 11 being secured to the inner faces of these uprights. B The improved roof is formed of plates, such as 12, 13, 14, 15. Each latehas its orm flanges,

at the ridge of the roof, are inclined backdetailplan View of the roof,-

t-he line 2- 2 of Fig. 1; Fig.-

der heavy loads, as A'are wood of mtalfar'e usually P` wardly, .so that they assume a vertical position when the plates are in the inclined position they "assume in the formation of a' pitched roof, the ridge flanges ofthe in'- clined plates, as 14, 15, lying side by side and being secured together, as by means of rivets 20. The eave flange of each plate eX- 4tends downwardly outside of an cave plate 21 secured to the outer faces of the uprights 10 and preferably extending "from end to end of the car, the flanges 18 'being secured to this eave plate, as byV means of rivets 22.l

The side flanges of adjacent plates -lie side by side andare' secured together, as by means of rivets 23. The lower ends of these side flanges may be cut away as necessary to fit within the cave plate 21, as shown in Fig. 2.

The outer `side iianges of the plates, as

12, 13, 'at the end of the car, are folded down` over the outer-face of the car end, as shown in Fig. 3, and are secured thereto, as bythe rivets 24. f

` The kcross seams in the roof at the juncture Vof the several plates are covered by plates 25 extending from side to side of the car and being lapped down over 'the ldepending` iianges 18 of the roof plates, and are secure to the roof plates, as by rivets 26. The ridge seam of the roof is similarly covered by a.

plate 27 extending from end to end of the car and lapping downwardly over the depending. iianges 19 of the end plates, and

lbeing secured tothe various plates, as by rivets 2S.

In a roof thus formed the ridge4 anges 16 supply the place of a ridge pole, and the side flanges of the plates provide the strength heretofore secured by the use of carlines. 'It 5 becomes unnecessary, therefore, to provide a framing for supporting the roof, and the latter will be rigid and inflexible and will contribute to t'he strength of the entire structuie Qf the car. y

A running heard 29 may be mounted up 'n brasil c 30 accuraat@ the'ridge .0f 'the stabil' )here las made @f flat vplates inaybe given'any'desired crosssectional configuration.

lI claim as my invention:

1. A carl roof formed `of a plurality of sheet metal plates, each plate extending from the ridge of the roof to the eaves and having a downstanding continuousfiange along its sides and its end at the ridge of he geeft Jdie flanges of adjacent plates bein together.

2, A Car roof formed ef a piniaiity 0f 5 `heet .nie'l'alplaie each plate extending from iherdge @i the -i'eofto the eaves and having a deninst"ndingx continuons iangealong its sides anfiiis end at. the ridge of the iof, the

anges'o' z l-djacient plates .being in face. te

ng edge of adjacent plates and being riveted.l to each of Such plates;l Y A VVitne's'seS gf' YLoIs' K. GLLsON, LA. HELMICH- LEWIS T.. CANFIELD..
